Subject: scripts/kallsyms: suppress build warning
From: Himanshu Chauhan <hschauhan@xxxxxxxxxxxxx>
Suppress a warn_unused_result warning.
fgets is called as a part of error handling. It is called just to drop a
line and return immediately. read_map is reading the file in a loop and
read_symbol reads line by line. So I think there is no point in using
return value for useful checking. Other checks like 3 items were returned
or !EOF have already been done.
